Application led December 26, 1912, Serial No. 738.614. Renewed September` 26. 1917.` Serial No. 193,389.

lie it known that I. muxn'i LA'rnAu, a citizen oil-the United States, residing at Beverly. in the county of Essex and State of Massachusetts. have invented certain new and useful Improvements iii Shoe-Sleivingig Machines: and I do hereby declare thefollowing to he a full. clear. and exact descrip tion of the invention, such as will eiiahle others skilled in the art to which it appertains to make and use the same.

The invention relates to sewing machines such as are used in the manufacture of boots and mechanisms for facilitatingr the removal of a completed shoe fi'oin the machine and the .starting of the seam at the beginning of the sewing operation on the succeeding shoe. 'l'he object of the invention is to provide novel aud improved mechanism for auto inaticallv reversing the machine totree the thread from the needle. and for autoniati call v cutting the welt at the completion of the sewing of a shoe. and for holding the welt end at the beginning of the seam-of the next succeeding shoe. and to further iinprove various mechanisms of the machine.

'l`o these ends the inventionvcoiisists in the features of construction and combinations of parts hereinafter described and referred to in the claims. o

The various features of the invention will be readily understood from an inspection of.

the accompanying drawings and the following detailed description of the machine illusti'ated therein.

In the drawings. Figure Vl is a side elevation of a welt and tiii'n sewing machine enihodving the invention in its preferred form; Fig. 2 is asimilar View showing the parts at the end of the cam shaft on a larger scale;

arts carvertical sectional view on line 4l. Fig. Q; Fig. 5 is a horizontal sectional view on line 5 5. Fig. :i: Fig-(3 is a verti al sectional view on line Fig. 3: Fig. T isa vertical sectional view on lline T T. Fig. 3; Fig. 8 is a vertical sectional view on line 8-8, Fig.

tional view on line 11-11, Fig. t5; Fig. 12

is a detail plan view partly in section showing the clutches for operating the mechai'iisin which reverses the cam shaft and'for operating the welt-cutting and holding device; Fig. 13 is a vertical sectional view on line Iii-13. Fig. 12; Fig. 14 is a vertical sectional view on line 14x-14, Fig. 1l; Fig. 15 is a vertical sectional view online 15P-l5, Fig. 11; Fig. 16 is a sectional lview on lline ltr-1G, Fig. l; Fig. 1T is a detail elevation showing the whole elevation of the stopping mechanism shown fin Fig. .16, the brake carrying disk being removed Vto show the parts behind it: Fig. 1H is'a sectional view on line lfl. Fig. IT; Fig. Il) is a vertical sectional view on Iine'I9--IS-L'I4`ig. 8; Fig. 20 is a horizontal sectional view on line 20-20, Fig. 19; Fig. 2l a vertical sectional view 4through the brake applying cylinder and piston; Figs. 22. 23 and 24 are sectional elevations showing parts of the mechanism for moving the welt holding grippers with the shoe during the sewing of one or more stitches; Fig. 25 a detail side elevation showing the welt holding grippers'and cut tei: Fig. 2G is a plan view of the parts shown in Fig. 25; Fig. 27 is a side elevation of the parts showiivin Fig. 25; showing the other side of the parts: Fig. 28 is a sectional elevation similar to Fig. 2T. showing the parts in a different position: Fig. 29 is a sectional view on line 29-29. Fig. 26: Figs. 3() and 31 are details Vof the thread cutting and holdingdevice: and Fig. 32 is a vertical sectional view through the axis of the driving clutches which are mounted in the base of the machine. l

The invention is shown as embodied in a welt sewing machine having the construction and mode of operation of the machine illustrated aiild described in the application of Andrew Fippler. Serial No. 447.542. tiled August 8. 1908, on which Patent No.
